How Do I Reverse A List Or Loop Over It Backwards?

There are several ways to reverse a list or loop over it backwards in Python. Here are three common methods:

  1. Using the reversed() function:

    my_list = [1, 2, 3, 4, 5]
    reversed_list = list(reversed(my_list))
    for element in reversed_list:
        print(element)
    
  2. Using the [::-1] slice notation:

    my_list = [1, 2, 3, 4, 5]
    reversed_list = my_list[::-1]
    for element in reversed_list:
        print(element)
    
  3. Using a traditional for loop with range:

    my_list = [1, 2, 3, 4, 5]
    for i in range(len(my_list)-1, -1, -1):
        print(my_list[i])
    

All three methods will produce the same result, which is looping over the list in reverse order.
